Application filed February l5, 1908. Serial No. 361.209,

To au w/wm it may concern: 1 Be it known that I, WALTER O. AMsLnn, acitizen of the United States, residing at Pittsburg, in the county ofAllegheny and State 5 of Pennsylvania, have invented new and usefulImprovements in Glass-Melting Furnaces, of which the following is aspecification.

My invention relates to glassemelting xo furnaces, and more particularlyto that class of continuous melting-furnaces comprising a tank dividedinto two compartments by a bridge or partition wall.

In furnaces of this class as heretofore coni5 structed much trouble andexpense has occurred by reason of the wearing away of that portion ofthe bridge-wall nearest the passage connecting the two compartments ofthe tank.

The primary object of the present invention is to provide simple andeiiicient means to preserve the bridge-Wall and to jrevent thedisintegration of that portion of t e wall nearest the assage connectingthe two conn 25 partments aliove referred to.

To this end my'invention consistsof a glass-melting furnace in the noveifeatures of construction and in the combination of parts, all as fullyhereinafter described and 3o claimed.

in the accompanying drawings, which illustrate applications of myinvention, Figure 1 is a broken vertical longitudinal sec-1 tional Viewof a furnace embodying 1nyin- 5 5 vention; Fig. 2, a similar detailview, par ticularly showing the central portion of the bridge-wail; Fig.3, a detaii horizontal sectional view of bridge-wall, taken on line iiiIII of Fig. 2; Fig. 4, a vertical sectional 4o view taken on line IV Vof Fig. 7, showing additional cooling-plates Fig. 5, detail views of thecooling-plate employed in the form ci Fig. l; Fig. 6, a detail side viewof the additional cooling-plate shown in Fig. and 45 Eig. 7 a detailhorizontal secticnai view showing the location of the cooling-piates inthe bridge-wall.

Referring tothe drawings, the tank of the furnace, as illustrated and aspreferred, is 5o' formed with a suitable bottom ioor i and supported vbycolumns '2. ilie tank is divided into two compartments 3 and 4 lbybridge-Wall 5. Bridge-wail 5 extends entirely across the furnace and isformed with an opening or air-space in addition to the air-space 6 thebridge-wall is constructed 'with a centrai passage 7, designed toconnect the two compartments and permit the passage of recit-en glassfrom the--molting-coinpertinent to the working-out compartment 4.Located within the opening or airspace 6 and near the 7 i employ meansfor effecting a circulation of a cooling fluid for the purposes ofcooling that portion of tho waii moet likely to he affected in theoperation of the furnace.

in the term of Fig. i l employ an an ular late formed with a pluralityof uid- Q, an inlet tap-hole l0, and an outet tap-hole il. Said iniotand outlet each communicate with pipes l2, adapted to convey a te andfrom the plate 8. The arrangement ci the passages in said plate isgarticulariy shown. in the detail views of i 5 in the form of Fig. 7 inaddition to the piate 8 E rave shown vertical cooling-platcs 13, saidplates )sing joined by cross-rods let;

l. in a glass-melting furnace, a tank, a bridgeewaii dividing the tankinto compartments, a passage connecting the compartments, means in the-tirifige-wall comprising a plate formed with passages for effecting acirculation of a cooling iluid near the passage connecting 'tlnpartrnents therein.

in a glass-'mening' furnace, a tank, a bridge-wah formed li ai.;airspace dividing the tank into compertinents, a passage ccnnecting thecompari rients, means in the airspace electi a circulation'of a coolingiiuid near the 23. in i bridg 4 urnace, a tank, a f with an airspacedividi two compartments, a

i compartmentsf. and "mais i-ecatfd in the airjspace i id above and It.in a ng iurnace, a tank, a irridge-walirdivif g the tank into two comnpertinents, a passage connecting the two compartments, and acooling-fluid plate located in. the bridge-wall above and near the aconnecting the compartments.

n a glassenelting furnace, a tank, a bridge-wall t ividing the tank intotwo coinpertinents, a passage connecting the compartments, an angularcooling-plate provided Withpassages for the eiculation of a coolingfluid therein, said plate located in the bridgewall neai the passa-geconnecting the two compartments.

In a glass-melting.ffiiiiiaee, a tank, a bridge-wall dividing the tankinto tw@ coinpartnients, a passage connecting the eoinpartn'ients,ineens in the bridge-wall, located near the passage connecting the twocompartments, foi' elleeting a circulation. of a cooling fluidcomprising a horizontally-disposed cooling-plate and verticalcooling-plates.

7. Ina glass-Tnelting furnace, a tank, a l' ridge-wall formed with auair-space dividing the tank into two compartments, a passage connectingtlie two compartments, an angulaii cooling-plate provided with passagesk for a cooling `fluid located in the air-spaee l and near the passageconnecting the two compartments.

8. ln a glass-ineltinv furnace, a tank, a bridge-wall' formed witlli anair-space dividing the tank into two compartments, a passage connectingthe oon1partments,an angular horizontally-disposed Cooling-plateprovided with passages for a cooling luid, Vertically-disposedcooling-plates also formed with passages for a cooling fluid, saidcooling-plates located in the air-speee and near the passage vconnectingthe two compartments.

In testimony whereof I affix my signature in presence ef two subscribingwitnesses.
